Abstract
Heavy equipment is designed for operation in a substantially-repetitive work cycle that includes lifting, rotating, and lowering steps. The heavy equipment includes a generator, an electrical bus, an energy storage component, and working components. The generator provides a substantially constant electrical output to the electrical bus, which is communicated to the working components. As such, the working components of the heavy equipment are driven directly or indirectly by the electrical output of the generator. The controller selectively couples the energy storage component to the electrical bus, and the energy storage component is configured to store electricity provided by the generator, and to provide electricity to the working components by way of the electrical bus. The electrical output of the generator is less than the power used by the heavy equipment during a portion of the work cycle, and the controller couples the energy storage component to the electrical bus to supplement the electrical output of the generator during the portion of the work cycle in which the electrical output of the generator is less than the power used by the working components of the heavy equipment.
